Attaching leads/pigtail to molex

[saturated]

I have a harness from a boat anchor power supply I don't want to cut it up so I desoldered the male connectors from a circuit board 🛹

Here they are with the harness (the big 🔌 plug top right connects to the PS)

I just need to attach some wire/leads whatever to the male doodads
I think the pins remove and I attach wire or just get pins with wire and install

Thanks

Looks like I need to get the old pins out which are male on one end and through hole on the other

Then replace with male crimped to wire

Duh

Idk if this is gonna be useful for anything

I'm gonna try the plus and minus 5v on my Op-Amps 

It would be cool 😎 to find a good use for it it's built like a tank.  I just don't have an immediate need for 49v DC. 

I need to figure out why when I measured across the filter cap I got 78v.   

Also these transformers are kind of a trip it looks like all of the terminals are on one side.

That fan is a beast too.  Crazy how much lint dust bunnies 🐇 🐰 and mud daubers and stuff was inside.

I really like TO-3 they are cool I looked them up

The one with the sweet pic 😍 of two diodes is a twin rectifier 

The 2N3055 is a 60v NPN transistor and apparently is still available.

Interesting.  I've never seen that in a TO-3 package before.  I guess that was before they had the big power bridge rectifiers we use now.

Thank you sir I roughly eyeballed the male pins and I came up with about 1/16 and that is about 0.063 then I see they have 0.062 and 0.93 (among others I presume)

Then I looked at the extractor tools and stuff and kinda groaned at the startup cost 

Sure would be nice to have those tools though after remembering the times I dealt with them in the past one time repairing a lamp

Old guard power supplies, not much use today.

*Guess* +/-5V was for old style Logic boards (where 5V supply was the standard) and +48V is standard for classic *telephone* lines.
The whole bunch might have powered some kind of telephone central, maybe in a small neighborhood or large Factory central.

Analog regulated supplies were very inefficient, hence the need for heatsinking and fan cooling; today any old computer supply can offer 5 Volts at 20-30-40 Amps for peanuts.

I'm gonna try the plus and minus 5v on my Op-Amps 

Way too low for that, they will work but poorly.

+78V is raw unregulated voltage, then down regulated to very clean 48V
perfect for a 100W into 4 ohm power amplifier, single supply of course, like the Acoustic Control Corp Guitar and Bass amplifiers.



You already have the +78V supply, the rest is easy.
Driver and power transistors have modern equivalents, you would need to draw your own PCB.

Power transistors are selected/good quality 2N3055 and you already have them.
You can also use the aluminum sheet heatsinks.

You are 90% there.

You can also build any preamp you like to drive it.

+/- 5V supply can probably give you raw +14/16V if halves put in series.

Not much use for the single +5V one.

WOW  a wealth of information 

Thank you so much sir nice to hear from you 

HAPPY HOLIDAYS

Btw for clarification this is where it came from
My friends wife had an answering service company for years
This satchel/case is ridiculously heavy even with the PS out of it

On the side opposite the PS all these little boards slide in

I had imagined something Phone related, was very close

Lots of nice stuff to cannibalize from those boards, at least a lot of good quality relays.
